I am currently building management packs for Forefront Client Security as well as for McAfee, as these are the main two antivirus applications our customers are running in their server environments.
The main idea is to capture the events on the client (agent) side to allow the respective server/service owners to also have a view of the AV status on their servers. It is not to replace the FCS or EPO management servers at all.
Now, since I am still in build phase, I thought I would open up the floor for requests. If you would like such a management pack, and could request features, leave a comment to let me know what you would like to see :)
